Optical coherence tomography angiography (OCTA) offers noninvasive, high-resolution imaging of retinal and choroidal vasculature. This review highlights OCTA
Area of Science:
- Ophthalmology
- Medical Imaging
- Biomedical Engineering
Background:
- Optical coherence tomography angiography (OCTA) is an advanced imaging technique.
- It visualizes the microvasculature of the retina and choroid.
- Understanding its principles and applications is crucial for clinical practice.
Purpose of the Study:
- To review the fundamental principles of OCTA.
- To survey the current clinical utility of OCTA.
- To identify the strengths and adoption barriers of OCTA technology.
Main Methods:
- A comprehensive literature review was conducted.
- Editorial discussion of current OCTA applications was included.
- Focus on advancements in devices, algorithms, and pathological observations.
Main Results:
- Recent advances include improved scanning speed, signal-to-noise ratio, spatial resolution, and field of view.
- Optimized algorithms reduce artifacts and enhance image processing.
- OCTA has demonstrated utility in diabetic retinopathy, AMD, CSR, RVO, and uveitis.
Conclusions:
- OCTA provides noninvasive, high-resolution volumetric scans of retinal and choroidal vasculature.
- It offers valuable data to supplement traditional angiography in chorioretinal diseases.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
